Great! I had used them before with continual problems with the previous plumbing. They answered my questions and suggested that a complete redo would be desirable. When my 15 year old dishwasher broke again I called in a very reliable repairman. After removing the dishwasher, he told me that the plumbing was not up to current code and I couldn't put in a new dishwasher until I had it fixed. Besides problems with the dishwasher: - the hot/cold lines to the sink were reversed, - the lines connected the dishwasher and the garbage disposal in a way that sent the dirty water back to the dishwasher, requiring us to clean the dishes before using the dishwasher, the hot water line was connected to the ice maker resulting in mineral deposits on the ice, the shut off valves were almost impossible to reach for the hot water dispenser and the garbage disposal, and - the pipe to the dishwasher was not in the correct position to properly drain the dishwasher. He repaired all these items and reduced the amount of pipes so I have more room beneath the sink. It only took 3 hours for him to remove all the old plumbing, repair the drain, and put in new pipes and valves. My kitchen was clean when he finished with no disruption to our household. Outstanding!
